Hi,

I'm using libvlc to read multiple videos, but I need them to be synchronized, either with each other or both with an external clock. Is it possible to do so with libVLC?

Thanks a lot in advance,

You can render synchronized inputs with (lib)VLC using the slave-input option. But that requires that the inputs are actually synchronized to begin with (i.e. have identical timestamp origins). But most of the libvlc video control API assume there is only one video, and won't quite work.
